Application April 20, 1948, Serial No. 22,197

This invention pertains to flint ignited cigar or cigarette lighters ofconventional forms. These lighters are preferably made relatively smallso they can fit conveniently into the users pocket and be readilyavailable for use in lighting cigars or other objects that require asmall active flame to ignite them. These lighters usually have aprojecting lighting wick immersed inside the fuel reservoir of thelighter for the greater part of its length, so as to soak up the fueland by capillary action transmit it to the projecting end.

'This projecting end is ignited by a pyrophoric disposed adjacent thewick, through the use of a mechanical striker. The projecting wick endpasses through a tubular stem, over which a cap is placed during thenon-use of the lighter, to prevent evaporation of the liquid fuel. Thefuel liquid is poured in throughan opening having a flush screw closure,at the bottom of the lighter reservoir, when the latter is being filled.This invention pertains particularly to the form of cap to be used overthe stem of the liquid fuel can, and its added feature of forming a keyor tool on the end of the cap of the fuel can for the removal of thescrew closure in the bottom of the lighter.

The invention includes amongst its objects to provide a new and improvedform of cap for use in closing the stem of a can of lighter fluid thatwill avoid one or more of the disadvantages and limitations of the priorart.

Another object of the presentinvention is to provide a new and improvedform of a cap for use on lighter fluid cans that will be available foruse as a tool for the removal of the liquid fuel-orifice closure of thelighter.

A further object of the invention is to provide a new and improved formof cap for a lighter fluid can that will be so attached to the lighteras to be less liable to loss therefrom.

Other objects will become apparent as the details of the invention arefurther set forth.

For a better understanding of the invention and its objects, referenceis made to the appended drawings and the description following herein.These drawings and description portray a particular form of theinvention by way of example and indicate the principles on which it isbased. While the claim included therewith particularly emphasizes thescope of the invention.

The drawings include: 7

Figure 1 is a plan view of a lighter fluid can,

the lighter can with its cap and protector shown in section to show itsinner construction; and

1 Claim. (01. 222-192 Figure 3, is an endelevation showing the manner inwhich the cap is used as a toolfor removing the filling orifice closureof a lighting device.

Similar reference characters refer to similar parts throughout thedrawings.

In the particular lighter fluid can shown in the drawings, a casing I0forms a container for the liquid fuel, used in supplying lighting fiui'dto the lighter II. The stem I2 is exteriorly screw threaded in aconventional manner, to receive and hold an interiorlyiscrew threadedcap I4. This cap I4 is preferably of magnetic material and is attachedto the casing I0, so it will have a strong tendency to adhere to "it. Ascrew driver tip or tool or key I5 is, provided on the cap and extendsabove it as shown in Figure 1. The screw driver tip or tool or, key isarranged to fit into the slot I6 of a countersunk screw or closure headI! used as a closure-to the filling orifice of the lighter. Thisorifice: and closure is usually located'at the bottom of the lightercasing I I.

The countersunk screw I'I, like the cap I4, is made of material havingmagnetic characteristics. The lighter is of conventional design and isso commonly known and distributed throughout commerce that it is notbelieved to require further description in this specification. Aprotector I9 consisting of a hollow cap-like structure of plastic orother suitable material, is slipped over the cap I4, on which it fitsfrictionally, and covers the latter and its screw driver tip or tool I5.It may be readily removed. It provides an attractive appearance to thecap portion of the casing II). The main purpose of the cover orprotector however is to prevent the screw driver tip from tearing theuser's pockets, or injuring him in other ways. The cap I4 is fitted witha ring I3 which allows the cap to turn and is connected by a chain 30.

In the use of the device, particularly in the process of filling theliquid fuel reservoir in the lighter II through the orifice, theoperator removes the protector I9 and unscrews the cap I4 from the stemI2 and removes it, with his hand by twisting on the tip I5. Then heapplies the screw driver tip I5 to the slot I6 of the screw IT. Theturning of the tip I5, as the cap I4 is rotated, loosens the screwclosure I! and removes it from the bottom of the lighter II. As the tipI5 is magnetic and the screw I! of similar material, it adheres to thelatter on removal, by the attraction of each to the other. This preventsthe screw from being lost, which frequently happens in the use of theordinary lighter. The operator removes the screw II by hand through 3the aid of the cap l4 and after the liquid fuel has been poured in,replaces it in the orifice. The cap I4 is provided with a washer 32 toallow it to seal tightly on stem 12. Then the cap I4 is replacedon thestem I 2, and the protector i9 repositioned over it.

It should be noted, that the cap I4 is closed in at its top 20 to makeits closing effect complete, and from this top, the screw driver tip ortool projects in an integral manner. There are several ways in which thetip. 15 could be attached during manufacture, but whatever is chosen inpreference, requires that it be sunlciently strong to withstand thestresses incurred during the unscrewing or screwing or removal of theclosure H.

The device has a number of practical advantages, the screwdriver tip ortool i5 is available at all times for use with the lighter, it is ofconvenient size and type for the work required; and the tip forms a fiatsurface suitable for easy manipulation by the fingers of they operator.The magnetic qualities introduced in the lighter screw [1 and cap [4keep the parts accessible, instead of free to Wander oif withoutcontrol, as is usually the case. The protector 14 keeps the tip 15 freefrom injury. This protector may be kept placed. on the cap l4, when thelatter is removed and then taken off when the ti is to be used. Thus incase the casing 10 is dropped it will have its tip protected by thisprotector. It is to be understood that the screw driver tip 55 may be ofany form suitable as a tool for the removal of theclosure .or screw. [7,and that the material of which the casing, cap and. closure 'are' mademay bemagnetic in the form of iron or other metal or of plastic or anyother composition made to-includemagnetic qualities, as is now knowninthe arts.

While but one general form of the invention is shown in the drawings anddescribedin the 4 specification, it is not desired to limit thisapplication for patent to this particular form, as it is appreciatedthat other forms of construction could be made that would use the sameprinciples and come within the scope of the appended claim.

Having thus described the invention, what is claimed is:

A fuel container for dispensing liquid fuel to a lighter, comprising acasing, a hollow screw threaded stem at the dispensing end of thecasing, said stem terminating in an open end, a cap threadedtosaid stem,said cap being domeshaped and terminating in a tool tip usable to removethe screwthreaded closure of the lighter, said cap being magnetized toretain'the screwthreaded' closure of the lighter, an internal washerbetween said stem and the internal wall of the cap, said washer closingthe open end of the hollow stem when the cap is screwed in place, saidcap having an external peripheral shoulder thereon, a chain retainingsaid cap to said cas- 7 ing when the cap is unscrewed, and a cover overthe cap in frictional engagement therewith and resting on said shoulder,said cover providing a shieldover the tool end of the cap.
